     Notes on tags used in MITgcmUV
     ==============================
 
+checkpoint52d_post
 o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
+o changes to permit hi-res, cubed-sphere, configuration
+  - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
+  - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
+  - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
+    of surface winds for the cube
+  (A verification experiment, based on global_ocean.cs32x15, but with
+   pkg/seaice turned on and with on-the-fly interpolation from the NCEP
+   Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
+   complete with example surface forcing files and matlab scripts to look
+   at the output and compare it with that of global_ocean.cs32x15.)
+o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
+   but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
+   to conform to the common rule.
+o check-in the first version of the coupler + interfaces for multi-components 
+   set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
+   - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
+   - atmosphere: use pkg aim_v23 ; no sea-ice for now. 
+   - ocean and atmos. share the same horizontal grid (no interpolation).
+   - exchanges between component and coupler is done in forward_step
+o new verification experiment, cpl_aim+ocn: 
+   coupled ocean - AIM atmosphere on cs32 grid.
